In the mean time try turning your system clock back to the beginning of the month (it appears to be a time related bug). Then you can install Nebula, get your SER file, and send in your SER file to get your registration.
It's funny that only my console stopped working suddenly (I created different categories) . I found that the INT.n2p disappaered in the console program folder and it worked again after it was replaced........
please note: setup installers are trying to install init files which expired. THOSE INIT FILES EXPIRED, and it means that if you didn't install a license key over (or the license key was wrong or not correctly installed), your nebula expired too, and you can't run a setup version now.
I'll substitute setup versions for all plugins today, so you'll be able to generate SER files again.
So here what happened: INIT file copied by "setup installers" expired, but they were supposed to be substituted by the license key. At the moment if you try to run a setup version you have the same issue: you can't run nebula the first time because those INIT files expired. Wait for a new setup version.
If your nebula stopped working, simply you was not running correctly the key, or the key was WRONG or you was not running the key at all. If you installed the key over and now it's working it means the key was RIGHT but not installed correctly. A wrong key would expire immediatly AGAIN, and it's very unlike that it was expiring in the same expiration day of the INIT key located in setup versions.
Although my Neb3 Pro is still working fine (both commercial and third party libraries) I checked the Disk page and it says "REGISTERED: CUSTOMER" Is this correct? Will I have the problem as soon as the "Init" files expire? - if they do that is. I run the license installation again just in case but nothing changed in the Disk page.
